Common complaints

Concerns regarding PA care and knowledge for severe issues

"If I could give more stars I would. Stephanie Lynch was personable, and very thorough. She addressed all of my concerns and asked all the right questions."

"Unfortunately, the PA they feed me to knows almost nothing, which is concerning regarding my care, especially since I have some rather severe issues."
